This is the question the researchers tried to answer by doing a 28-day long experiment with 20 recreational bodybuilders whose average age was 22.

I wouldn't say useless. Personally I don't know why 20 somethings would ever need a boost in testosterone, maybe during PCT. I think people in that age group have plenty of natural testosterone and don't need AAS anyway. Study doesn't prove anything not already blatantly obvious. If you already have plenty of natural testosterone surging through your body, OTC test boosters won't do much of anything.

i've said for awhile that daa never gave gym results...no strength, body comp or aggression in the gym

however if you can guarantee an increase in test during post cycle therapy with using daa, the price is cheap enough...so why not throw it in a post cycle therapy, i've also found that daa mixed with your favorite test booster is the way to really get results

it's been awhile since i listened but i believe on muscle college radio that Ben Escro also said the DAA hype has gone too far

Like I said before, you young guys aren't gonna notice much from OTC test boosters. Just because it "doesn't work" for a certain age group doesn't mean it "doesn't work" at all. That's just ridiculous.

As to DAA, I understand that it is now recognized as having the greatest benefits to the older contingent, following natural T decline.

For that reason, I will be using it in December - just to see fro myself.

It is generally in the over 35, forums for those seeking TRT, and the >30 folks that are seeing that it really doesn't work all that well. In fact, many of us have found that it lowers test and increases e2. I think everyone needs to determine what works best for them when it comes to non script supplements, but in my opinion, DAA is worthless.

Don't have full text, but didn't this also use regular DAA as opposed to Na-DAA as well? How much difference do you think that would make?

All I know is the authors' conclusions are awful. They think DAA oxidase was elevated in response to prolonged supplementation, hence the lack of DAA effects at the 1-month mark. But there is a 3-month study showing T elevation, and there is no reason to believe that DAA-oxidase is downregulated in infertile men

The above is my own opinion and does not reflect the opinion of PES

I thought the general consensus was that test boosters in general were just fancy mood/libido enhancers with limited ability to help people with low test(Older people) build muscle. I've taken DAA before and enjoyed it, but had no impact on gains.

the italian study was three months but they only tested testosterone for 12 days

one of the reasons they concluded that was the blood levels of DAA not being very elevated at 30 days

However they didnt do any earlier blood draws to compare against. the study design was flawed in that respect

I think its funny how people just ignore coops and arnolds posts on the matter. Also if you read the article they were using free form DAA and not sodium or the chelated version. Wouldn't that make a huge difference or am I crazy for thinking that?!!!?!!!!

My dad who is in his 50s has been using DAA and erase for three month stretches and over the past year has lost 20+ lbs, and received a lot of strength and muscle gains. Granted he does manual labor and is in the gym 4 days a week with a solid diet but that simple addition has helped him immensely and with out TRT which his doc wont prescribe to him.

I like it because of the increased libido, mood, faster strength gains, and faster muscle gains. It also allows me to keep my strength while I cut calories. It's night and day as far as strength gains go, between being off it and being on it. I really don't consider myself a bodybuilder, but it's definitely not useless to me.

My dad says there is a night and day difference in the month of two that he takes off. Mr. Arnold may have an answer to this would it be ok to stay on DAA and erase year round for a guy in his 50s or would there be adverse effects?

Wow, I am 46 and love DAA - it allows me to lift like I was 25 - I would not have 1/2 the muscle I have right now without it. I seem to get lasting gains (small, but still gains) each cycle. Just MOP.

Well it's ingrained in bodybuilding because it raises test, and laymen like to think that fluctuations within normal ranges will have have "steroid" like results. Might be useful to older males and is cheap enough to test out, in fact I bought a tub for my dad to test out. I used it a couple times, felt enough difference in mood to justify the cost every now and then. If younger people see gains from it I'd chalk it up to placebo, but if using it makes them feel they can add a little more weight to their lifts more power to them.

Depends what product I use. Lately I've been cycling on and off Test Powder. So in that case, yes. I've used PP TCF-1, TestForce 2, a few others I can't recall the names of. I first used the nutraplanet bulk powder when it was first introduced, loved daa ever since. I think it was 2010. With bulk stuff I never added anything to it.
